Leaders from the US, China and the EU celebrate agreement reached in Paris, with Barack Obama warning there is hard work ahead

World leaders have hailed the 11th-hour climate deal reached in Paris on Saturday, claiming it provides the “best chance we have” of saving the planet from catastrophic climate change.

As the dust settles on what politicians insisted was a historic agreement, senior figures from the US, China and the EU welcomed the deal on Sunday – despite misgivings among climate scientists and campaigners who said it did not go far enough.
